Unfortunately there is no human readable settings information in the GoPro MP4 file.  However there are few bits that contain the camera's information. Hypoxic wrote a tool to extract the GoPro settings and the times of the highlight tags. This tool was made for the GoPro HERO4 but may work for older cameras. Leave feedback on HYPOXIC's Facebook page or git repository if you have suggestions.   For MAC OSx GoProInfo v. 0.0.5For PC GoProInfo v. 0.0.6 Based upon Bento4, the...

We spend a lot of time working on the interoperability between our products and GoPro Cameras. In doing this we uncover some features that may or may not make it into future products. Here are some of the bigger points: Multi Cam The camera's firmware enables multiple GoPro HERO4s to be synchronized (genlocked) to prevent inner-frame latency issues between cameras. This enables bullet-time and 360deg cubes to capture the exact same instant on all cameras. It also simplifies the post operations since...

I just learned something tonight after wondering what where those LRV and THM files on my GOPRO HERO3.  Turns out the THM is just a JPG used in the future as a thumbnail for the video and the LRV is a super low res version of the video (432x240). I'm assuming the latter is for playback via wifi or simply as the streaming buffer when the smartphone is used as control. If you want to see this, just rename the...

I was looking for this but could not find it online so here it is: If you want to connect a GOPRO HERO3 to an aircraft radio all you need to do is buy a GOPRO microphone adapter or a  GOPRO combo cable and jack the speaker out of your radio to the microphone-in on the aforesaid cable. For instance I created a cable for our VXA-150 by using a 3.5mm 4 conductor cable and a 3.5mm 3 conductor cable like below:  ...
